🔍 Suggested Next Steps

1. Prioritize targets in failure or unknown state from the status matrix.
2. Validate backend health first; infrastructure failures can cascade into all targets.
3. Compare failed assertions with historical flaky routes before escalating.
4. Re-run the workflow with the same targets to confirm deterministic failure.
5. Reproduce locally using node scripts/test-e2e.ts <target> and matching environment profile.
